From Reactants to Products, and Vice Versa
A Song about Chemical Equilibrium
by Safiyyah Gordon

Hey my names Reactants
I’d like to tell you a story about
Me and my friend, Products
Oh uh-oh uh-oh oh

We were at a state
Of equilibrium
Oh uh-oh uh-oh oh

A dynamic condition
Reaction appears to have to stopped
But
It has not

The forward reaction
From me to you
Was equal to the reverse
From you to me
Oh uh-oh uh-oh oh

We were at a state
Of equilibrium
Oh uh-oh uh-oh oh

We had K sub eq
It’s the rate from you to me
Over the rate from me to you
An equilibrium constant

If I were a liquid
And you were a gas
We would have
A phase equilibrium
Oh uh-oh uh-oh oh

We were at a state
Of equilibrium
Oh uh-oh uh-oh oh

If I were a solute
And you were my ions
We would have K sub sp
A solubility constant

If I were acid
And you were my ions
We would have K sub a
An acid ionization constant
Oh uh-oh uh-oh oh

We were at a state
Of equilibrium
Oh uh-oh uh-oh oh

But things went wrong…

Le Chatelier’s Principle explains it all
Stresses affected us
Even disturbed us
Adjusted our equilibrium
Oh uh-oh uh-oh oh

But things went wrong…

Your concentration changed
Increases favoured you
Decreases favoured me
Oh no an equilibrium shift
Oh uh-oh uh-oh oh

But things went wrong…

Temperature Changed
Increases favoured the endothermic
Decreases favour the exothermic
Oh no an equilibrium shift
Oh uh-oh uh-oh oh

But things went wrong…

Pressure Changed when we were gases
Increases favoured the pressure-downers
Decreases favoured the pressure-uppers
Oh no an equilibrium shift

But things went wrong…

Adding Catalysts
And Inert Gases
They had no effect
No equilibrium shift
Oh uh-oh uh-oh oh

We were at a state
Of equilibrium
Oh uh-oh uh-oh oh

Oh Man, driving forces
Ethalpy
And Entropy
And Gibbs free-energy
Establishing our equilibrium

When Delta G equals 0
We knew we were at a state
Of equilibrium
Oh
Uh-oh
Oh
